BPFISH: Blockchain and Privacy-preserving FL Inspired Smart Healthcare. (arXiv:2207.11654v1 [cs.NI])

This paper proposes Federated Learning (FL) based smar t healthcare system
where Medical Centers (MCs) train the local model using the data collected from
patients and send the model weights to the miners in a blockchain-based robust
framework without sharing raw data, keeping privacy preservation into
deliberation. We formulate an optimization problem by maximizing the utility
and minimizing the loss function considering energy consumption and FL process
delay of MCs for learning effective models on distributed healthcare data
underlying a …
